About This Special Issue
Environmental isotope application is unique technique for investigating hydrological processes over much larger scale (spatial) and longer time scale. The methodologies are based on the use of naturally occurring isotopes for various hydrological problems encountered in water resources assessment developed and management activities an already established field of sciences recognised as “Isotope Hydrology".

The application of environmental isotopes (18O, 2H, 3H, 14C, 15N, 34S ….etc.) has given much better understanding of the following:

1. Delineating the aquifer/and or basin system boundary
2. Origin (genesis) of water
3. Hydraulic connection with surface water or between the different aquifer units related to one aquifer system or of multi-aquifer nature (systems)
4. Source and rate of replenishment

The application of isotope hydrology techniques to the major aquifers of shared water resources within African (Sahel and Sahara) aquifers has achieved the following objectives:

1. Develop a database of the isotopic composition (2H and 18O) of precipitation, surface water and ground water in the aquifer system/s of different African sub-regions
2. Assess the degree of interaction between the aquifers and surface water
3. Assess the influence of seasonal precipitation on recharge to bedrock aquifers
4. Develop a conceptual hydrologic model of the different hydrologic/ hydro graphic basins incorporating hydrologic, chemical and isotopic data from the regional aquifer/s
